Abstract
This study investigated the efficiency of decolorization of Acid Red 14 dye solution using screen cathode and compare the results with sheet cathode by electrocoagulation. A simple electrochemical cell was performed with horizontal mild steel iron disc anode and vertical stainless steel cylindrical cathodes (screen or sheet). Process duration, agitation speed, current density, initial dye concentration and electrolyte NaCl concentrations were the variables studied. It was found that screen cathode was more effective than sheet cathode. . For dye solution with 50 ppm and agitation speed 100 rpm after 18 min, 86 % color removal was achieved on using screen cathode, while 77 % color removal was achieved on using sheet cathode. The higher efficiency of screen cathode is attributed to the fact that screen acts as turbulence promoter and generate high turbulence intensity.
